Susan Colbourn is an international historian interested in the global Cold War, transatlantic relations, alliance politics, nuclear history, and archival declassification.

Her current project, entitled Euromissiles: A Transatlantic History, examines the rise and fall of the intermediate-range nuclear force arms race and its impact on the Atlantic Alliance, considering the intersections between East-West and West-West relations and the role of public opinion and social activism.

She recently received her Ph.D. in history from the University of Toronto. In 2018-2019, she will be a Henry Chauncey Jr. '57 postdoctoral fellow at International Security Studies at Yale University. She is also a fellow at the Bill Graham Centre for Contemporary International History.

Prior to her doctoral studies, she received an MA from the London School of Economics and Political Science and an Hon. BA from Trinity College at the University of Toronto.

She tweets about history and politics at @secolbourn and co-edits a blog on Canadian international history, Canadian Eyes Only.
